摘要： PURPOSE:To check occuring of cathode glow discharge concentrically on a small region of a cathode surface by providing a transducent anode to be connected with a positive potential terminal of a DC power source in opposition to a group of cathode elementary pieces through a discharge space. CONSTITUTION:A glow discharge tube for background lighting starts discharge by the properly impressed DC voltage between anode 5 and a back electrode 6 to generate cathode glow on the group of cathode elementary pieces and when the cahode elementary piece 8b, for instance, of the group of cathode elementary pieces starts discharge prior to others, voltage drop due to internal resistance rb between the cathode elementary piece 8b and the back electrode 6 becomes selectively big. Accordingly, the potential of the cathode elementary piece 8b tends to be biased to the positive side than that of the other cathode elementary pieces 8a, 8b... and the cathode glow having been generating on the surface of the cathode elementary piece 8b extends to the side of the cathode elementary pieces 8a, 8c... to obtain uniform cathode glow luminescence with no unevenness and missing on the whole surfaces of the group of cathode elementary pieces.

摘要： PURPOSE:To suppress a leak of light emission from pilot discharges in a device, by arranging the amount of distance between an anode and cathode less than the groove width of a pilot discharge region. CONSTITUTION:In the inner face of a front glass 1, blackened films 7 are provided for shielding the emission of light from pilot discharges. Anodes 3 are provided on top of said blackened films 7. These of the anodes 3, cathodes 4, dielectric layers 5 and the blackened films 7 are provided on two sheets of glass plates 1, 2 by the method of printing technology or the like. In the device, a mercury and Penning gas of neon and argon and the like are sealed. Though a distance d0 between the anode 3 and the cathode 4 is decreased for a smaller amount of discharge cell pitch of the device, the distance d0 is arranged in such a manner as to satisfy the relation of d0

摘要： PURPOSE:The discharge hole is extended up to 3rd conductor in order to enlarge the negative pole effective area per one unit of discharge hole. In this way, occurrence of cross-talk is preevnted without decreasing screen brightness even though the discharge hole is made minute to increase resolving power.

摘要： PURPOSE:To prevent nonuniformity of brightness or flickering of a display panel by forming a cathode of a complex obtained by mixing an insulating material of a prescribed proportion into an oxide conductor having a specific composition, lowering its discharge start voltage and the smallest discharge maintaining voltage, and eliminating deflection of a discharge area in a discharge cell. CONSTITUTION:A cathode which is formed of a complex obtained by mixing an insulating material of 20%-50% in weight % into an oxide conductor having a perovskite type crystal structure represented by a general equation La1-xalpha2betaO3 (provided that alphais Ba or Sr, beta is Co, Ni, Fe or Mn) is used. The insulating material is formed of at least one kind of Al2O3, ZrO2 and SiO2. Screen printing of Ag paste is carried out on a backing glass 1, and it is baked, so that an Ag substrate electrode 2 is formed. Laminate printing is carried out on the elctrode 2 by means of covar tight paste of Al2O3 mixture by using a screen printing method, and it is baked. The substrate 1 on which the cathode 3 is formed in this way, and a front glass base surface 6 provided with an anode 4 being a transparent electrode and a partition wall 5 are superposed upon each other through the partition wall 5, and glass frit is applied around there, and it is baked, and is sealed up airtightly, and gas is introduced therein.

摘要： PURPOSE:To obtain a large perspective angle by forming a great number of thin cathodes in the inside of a surface plate for perspective and a great number of thin anodes perpendicular to them in the inside of a back plate, and further providing insulating layers in parts of the surfaces of the cathodes. CONSTITUTION:An envelope is formed by a back plate 1 and a surface plate 2 for perspective, and a great number of thin cathodes 7 arranged in the inside of the surface plate 2 in parallel are provided, in which parts of the surfaces opposing to anodes 8 are covered with insulating layers 9, and the anodes 8 perpendicular to the cathodes 7 are provided in the inside of the back plate 1 in a parallel direction, and further insulating bulkheads 10 for forming scanning spaces are provided along the anodes 8, and the a discharge tube for display is formed. And therefore only the portions in the region of both ends of the cathodes 7 are exploded to the side of the anodes 8 and it is possible to obtain a large perspective angle even if the high density is made in the electrode arrangement because the cathode glow is generated in the only exploded region in discharging, and further it is possible to enlarge the area of each electrode and to reduce the resistance value.
